What's wrong with my n55

CollinHartwell · 05-08-2022, 07:46 PM

Recently my car has been stuttering/hesitating at around 1500 rpm during low acceleration. I had my spark plugs done less then 3000 miles ago. Anyone have an idea of what might be wrong?

Ignition coils? Vacuum leak? Do you have any codes when you run diagnostics?

Do you know what any of these codes mean?

They seem to be issues with a specific module. need to see the codes related to the engine. may be worth seeing a mechanic

hows your battery health? i just had a bunch of very odd issues resolved by replacing my 10 year old battery. and FWIW the battery showed no real signs of struggle, no slow starts nada.. maybe worth a shot?

+ 1. It shows you have a 2014. If that is still the original, it's time.

Do you think it could be the high pressure fuel pump or the low pressure fuel pump?

I'll for sure look into the battery too.

Very unlikely, why would you think that?

Just was thinking the stuttering and hesitating at low acceleration would most likely be cuz of lack of fuel or something related to that

Those problems would be more likely to occur under maximum load/fuel demand

Sounds good, it never has a problem when I floor it or even half throttle.
